General description

PBTTPD is a donor-acceptor based high crystalline conducting polymer. It has thieno[3,4-c]pyrrole-4,6-dione (TPD), which acts as the electron-withdrawing group. Bi(dodecyl)thiophene based donor groups facilitate the polymeric unit with crystallinity and low HOMO energy levels. It shows good hole mobility and open circuit voltage (VOC).
HOMO: -5.56 eV
LUMO: -3.10 eV
UV absorption: λmax = 572 nm;Eg = 1.82 eV
Solubility: This polymer can be dissolved easily in hot chloroform;hot chlorobenzene;hot dichlorobenzene

Application

PBTTPD is majorly used as a conjugating polymer in the fabrication of organic solar cells (OSCs) and organic photovoltaic cells (OPVs). It has a power conversion efficiency (PCE) of 7.3% and a VOC of 0.92V.
